Latest / The Mound Visit / 6 Metrics to Improve Lower Half Mechanics
Transcript
- 0:01Speaker 1: And we are back with the mound visit podcast. This
- 0:03Speaker 1: has been way too long since we have released an episode.
- 0:07Speaker 1: I want to say it was back in April that
- 0:08Speaker 1: we had one. And before that, I don't even know
- 0:11Speaker 1: when the last one was. I think it was over
- 0:13Speaker 1: a year prior to that. So I apologize for the
- 0:16Speaker 1: inconsistency and the lull of, you know, releasing some episodes. And,
- 0:21Speaker 1: you know, for me personally, I love podcasts. They're one
- 0:23Speaker 1: of my favorite resources when I'm driving to work or,
- 0:26Speaker 1: you know, driving around town, whatever it is that I'm doing.
- 0:29Speaker 1: I love being able to ingest 15 to 20 minutes
- 0:32Speaker 1: of an episode to develop myself, whether it's as a
- 0:35Speaker 1: coach or just personal endeavors and things that I like
- 0:38Speaker 1: to listen to. So hopefully we can get back on
- 0:41Speaker 1: track with this starting with today's episode. And we're going
- 0:45Speaker 1: to dive into some pitching mechanics. Specifically, we're going to
- 0:48Speaker 1: talk about force plate data as this is becoming very
- 0:53Speaker 1: popular in facilities and definitely in universities today. You know,
- 0:57Speaker 1: I feel like this year, every time I go on Twitter,
- 1:00Speaker 1: I'm seeing a new lab being put up at different
- 1:02Speaker 1: universities and not even necessarily Power Force schools. We have,
- 1:06Speaker 1: you know, mid-majors and some other divisions that are now
- 1:09Speaker 1: starting to get some of these pieces of technology like
- 1:13Speaker 1: force plates or motion capture systems. And it's really cool
- 1:16Speaker 1: to see just the advancement that the game has had
- 1:19Speaker 1: over the last couple years. And, you know, for us
- 1:22Speaker 1: specifically at our facility at Pitching Coach U, we've recently
- 1:25Speaker 1: have gotten some force plate mounds. We have the Axio
- 1:28Speaker 1: force plates that are, um, honestly have been phenomenal. And
- 1:32Speaker 1: I'm not trying to intentionally give a plug. I don't
- 1:34Speaker 1: have any affiliation or get a kickback or anything, but
- 1:37Speaker 1: they have been phenomenal, really good customer service. The plates
- 1:41Speaker 1: themselves have been working really, really well. Um, and I
- 1:44Speaker 1: had experience when I was with the twins using force
- 1:46Speaker 1: plates and, you know, these are very comparable to what
- 1:50Speaker 1: we used when, when I was with the Minnesota twins and, um,
- 1:53Speaker 1: the detail we get and how quickly we get the
- 1:56Speaker 1: data live as well as post-session to be able to
- 2:00Speaker 1: dive into the numbers and create plans for guys based
- 2:02Speaker 1: on what we're seeing has really been cool. So what
- 2:05Speaker 1: I want to do today is I want to dive
- 2:06Speaker 1: into some of those metrics that we look at. When
- 2:09Speaker 1: you get a force plate mount and you get some
- 2:11Speaker 1: of the CSV files for these, it is kind of
- 2:14Speaker 1: crazy how many different metrics you can actually dive into.
- 2:17Speaker 1: And a lot of them are similar. They're just going
- 2:19Speaker 1: to have a little bit of differences to them specifically,
- 2:22Speaker 1: whether it's the timing of when a certain force is happening.
- 2:26Speaker 1: But there's literally hundreds of different metrics that you can
- 2:28Speaker 1: dive into. And it can honestly be overwhelming if you
- 2:31Speaker 1: don't have experience with this or don't know what's important
- 2:33Speaker 1: and what's not important. And even though I have experience
- 2:36Speaker 1: using these, I'm always trying to learn more and dive
- 2:40Speaker 1: into new things and new ideas that maybe I hadn't
- 2:42Speaker 1: even thought of prior to this. So it's been really
- 2:44Speaker 1: cool just to educate myself more and to continue to
- 2:47Speaker 1: get better as a coach. and to understand this data
- 2:49Speaker 1: even better so that ultimately we can help our players
- 2:52Speaker 1: even more. And I think we would all agree that
- 2:54Speaker 1: that's the reason why we have motion capture systems. It's
- 2:58Speaker 1: the reason why we have force plates, a track man,
- 3:00Speaker 1: edutronic cameras, all these fancy tools. We're not getting them
- 3:04Speaker 1: just because we want to spend a lot of money.
- 3:06Speaker 1: We're getting them because we want to be able to
- 3:08Speaker 1: dive deeper into understanding how our pitchers move, what they
- 3:12Speaker 1: do well, and ultimately how they can improve. to win
- 3:15Speaker 1: more baseball games. Because at the end of the day,
- 3:17Speaker 1: that's what it's about, right? We're a lot of us.
- 3:20Speaker 1: If you have these pieces of technology, you're probably at a,
- 3:22Speaker 1: you know, a college or you're at a facility, whatever
- 3:25Speaker 1: it is. And our number one job is to get
- 3:28Speaker 1: these players better. So ultimately we can win more baseball games.
- 3:31Speaker 1: So if we're not doing that, then it's just an
- 3:33Speaker 1: expensive piece of technology. That's kind of just being wasted.
- 3:37Speaker 1: So hopefully today I can shed some light on some
- 3:41Speaker 1: of those details that you can dive into and, And
- 3:43Speaker 1: even if you don't have a force plate mount, right?
- 3:45Speaker 1: Like maybe you're listening and you're like, well, I don't
- 3:46Speaker 1: have a force plate mount, so this isn't going to
- 3:48Speaker 1: be useful for me at all. And I would say
- 3:51Speaker 1: you may not be able to get the details of
- 3:55Speaker 1: what the specific numbers are that you're looking for for
- 3:57Speaker 1: your players because you don't have any way to measure it.
- 4:00Speaker 1: But I think the concepts that I'm going to talk
- 4:01Speaker 1: about are ways and things that you can do with
- 4:04Speaker 1: your own players to still improve those areas of their
- 4:08Speaker 1: mechanics or there are different things that you can start
- 4:10Speaker 1: to program because you'll be able to see some of
- 4:12Speaker 1: these things on video or have an idea of what
- 4:14Speaker 1: they might do well or need to improve. So we're
- 4:17Speaker 1: going to dive into six metrics today and these aren't
- 4:21Speaker 1: the only ones that I look at or that you
- 4:23Speaker 1: necessarily should look at. I would just say that these
- 4:25Speaker 1: are kind of the bigger ones that we've seen have
- 4:28Speaker 1: the strongest correlation to velocity and also just allowing guys
- 4:32Speaker 1: to move better and honestly have better command too. If
- 4:35Speaker 1: we move better and more consistently on the mound, there's
- 4:37Speaker 1: a good chance we're going to throw more strikes and
- 4:40Speaker 1: ultimately we're going to have higher velocity as well. So
- 4:43Speaker 1: the first one I want to dive into, and if
- 4:45Speaker 1: you are looking at this on YouTube, you'll be able
- 4:48Speaker 1: to see my screen right now and see the graph
- 4:52Speaker 1: and the video that I have of a pitcher here
- 4:54Speaker 1: as an example. But if you're not and you're just
- 4:56Speaker 1: listening to this, I'll do my best to provide the
- 4:59Speaker 1: context and just the visual of what this might look
- 5:02Speaker 1: like so you can imagine this in your head. So
- 5:05Speaker 1: what we have here on the left is we have
- 5:07Speaker 1: our graph. So this is showing us everything that the
- 5:09Speaker 1: pitcher is doing with his back leg and his front leg.
- 5:13Speaker 1: And then here on the right, for those of you
- 5:14Speaker 1: that can't see, we have a video that is synced
- 5:16Speaker 1: up of the pitcher throwing so that we can actually
- 5:18Speaker 1: see this in real time, how he's producing force as
- 5:21Speaker 1: he goes through his delivery. The blue line here is Z-force.
- 5:26Speaker 1: So Z-force is force straight down into the ground. The
- 5:30Speaker 1: greenish yellow line This is Y force. So Y force
- 5:34Speaker 1: is the force we are producing pushing away from the rubber.
- 5:37Speaker 1: So just think about pushing towards second base and gaining
- 5:40Speaker 1: momentum down the mound. That is what Y force is.
- 5:43Speaker 1: And the red line is X force. So this is
- 5:45Speaker 1: the force we are producing towards the first base and
- 5:48Speaker 1: the third base direction. The first one I want to
- 5:51Speaker 1: focus on is this blue line, so peak Z. And
- 5:55Speaker 1: I'll be honest, Z force, it's important, but I don't
- 5:58Speaker 1: think it's the most important metric. We'll dive into this
- 6:01Speaker 1: here in a little bit when we start talking about
- 6:02Speaker 1: why force. But Z-force, as far as just like your
- 6:06Speaker 1: raw capability to produce force straight down to the ground,
- 6:08Speaker 1: it's important, but it's not the most important thing to me.
- 6:11Speaker 1: What is important is the timing that we're producing that
- 6:14Speaker 1: force and what this curvature looks like as you're seeing here.
- 6:17Speaker 1: This is a pretty smooth graph here. You'll see in
- 6:19Speaker 1: some examples where guys are just super choppy. It's almost
- 6:22Speaker 1: like a hill rather than like a sharp, steep angle
- 6:25Speaker 1: where they're producing force at a high rate. We want
- 6:28Speaker 1: to see more of that, more of that smooth and
- 6:30Speaker 1: more of that ramp-like buildup rather than just a little
- 6:32Speaker 1: bit of a hill. But before we get to that,
- 6:35Speaker 1: the thing that I want to talk about first is
- 6:37Speaker 1: peak de-weighting. So you might be wondering, what the heck
- 6:40Speaker 1: is peak de-weighting? I've never heard that term before. So
- 6:42Speaker 1: de-weighting is essentially when we are getting to our lightest point.
- 6:47Speaker 1: Most of the numbers that we are going to focus
- 6:48Speaker 1: on with force plates is how much force are we
- 6:50Speaker 1: producing from But the first metric I like to look
- 6:53Speaker 1: at is how little of force are we producing as
- 6:56Speaker 1: we are going into our leg lift. So I'll play
- 6:59Speaker 1: this video here and you'll see how this starts to move.
- 7:04Speaker 1: The lowest point that he is producing force is going
- 7:06Speaker 1: to be where this little downward dip is in this
- 7:09Speaker 1: blue line. And you can see he's at peak leg
- 7:12Speaker 1: lift right now. And when we get our lightest is
- 7:15Speaker 1: the moment we start to just descend down the mount.
- 7:18Speaker 1: It's that very first move where the peak leg lift
- 7:21Speaker 1: starts to come back down. This is where we are
- 7:24Speaker 1: just starting to absorb the ground a little bit and
- 7:26Speaker 1: we're not really producing a ton of force. The goal here,
- 7:30Speaker 1: generally speaking, is to get to about 50% of our
- 7:33Speaker 1: body weight. So if I weigh 200 pounds, I want
- 7:36Speaker 1: my force at this point to be right around 100 pounds.
- 7:40Speaker 1: If this is too high, that is a sign that
- 7:43Speaker 1: we are bending our back leg a little bit too
- 7:45Speaker 1: much into leg lift and we're trying to produce our
- 7:47Speaker 1: power and our force probably a little bit too early
- 7:49Speaker 1: in the And another way to look at this is
- 7:52Speaker 1: we're not going to be able to maximize the stretch
- 7:54Speaker 1: shortening cycle as well. So think of it this way.
- 7:57Speaker 1: If you were to do a squat jump, are you
- 8:00Speaker 1: going to produce a higher jump and more power if
- 8:03Speaker 1: I start tall, go down, and then rapidly accelerate up?
- 8:07Speaker 1: Or am I going to produce more power and jump
- 8:09Speaker 1: higher if I start at a standstill in like a
- 8:11Speaker 1: pause squat jump position and then jump up from there?
- 8:14Speaker 1: More times than not, you're going to produce more power
- 8:16Speaker 1: and you're going to have more elasticity if I start tall,
- 8:19Speaker 1: go down, and then rapidly go up. Now, we could
- 8:22Speaker 1: dive into some nuances here of different body types and
- 8:25Speaker 1: archetypes in regards to wide and narrow ISAs. This is
- 8:29Speaker 1: a conversation probably for a whole other episode. But the
- 8:33Speaker 1: point I would like to make is there might be
- 8:35Speaker 1: some guys where their jump height or their force production
- 8:39Speaker 1: is semi-similar from starting from a tall position doing a
- 8:42Speaker 1: counter movement jump as doing a squat jump. And then
- 8:45Speaker 1: you have other guys where there is a huge difference
- 8:47Speaker 1: and they really rely on that elasticity and that springiness
- 8:51Speaker 1: into the jump. Those are more of your narrows and
- 8:53Speaker 1: your widers or wide guys are going to be more
- 8:55Speaker 1: of your force producers that they might have, you know,
- 8:58Speaker 1: less of a need to have this super low D
- 9:01Speaker 1: weighting phase in order to capture more energy. I would
- 9:04Speaker 1: say that, you know, both camps could still benefit from it,
- 9:08Speaker 1: but we definitely want to make sure that our narrow guys,
- 9:10Speaker 1: think of just your taller, skinnier guys, they need to
- 9:13Speaker 1: rely more on that elasticity and more of that D
- 9:16Speaker 1: weighting so they can capture more energy as they're going
- 9:19Speaker 1: down the mound. Okay, so our next one now is
- 9:25Speaker 1: back leg peak Y. So back leg peak Y, that
- 9:28Speaker 1: is this green line here. The peak is where it
- 9:31Speaker 1: reaches the highest point here. And one thing that I
- 9:33Speaker 1: didn't say at the beginning of this episode is this
- 9:36Speaker 1: middle vertical line here, that is separating the back leg
- 9:40Speaker 1: from the front leg. So anything to the left of
- 9:42Speaker 1: that is the back leg. Anything to the right is
- 9:45Speaker 1: the lead leg. So right now we're focusing on what
- 9:47Speaker 1: our back leg is doing. And this green line here,
- 9:51Speaker 1: once again, is showing us peak back leg Y. So
- 9:55Speaker 1: Y force remember is pushing away from the rubber. And
- 9:58Speaker 1: this one is actually from what we have found so
- 10:00Speaker 1: far to be one of the leading indicators of throwing velocity.
- 10:04Speaker 1: Guys that have sharper and higher peak forces in the
- 10:07Speaker 1: Y direction tend to throw harder. This little green shaded
- 10:11Speaker 1: area here, this is what's called impulse. So impulse is
- 10:14Speaker 1: force being produced over time. So we could produce a
- 10:18Speaker 1: little amount of force, but if we're holding it for
- 10:20Speaker 1: a long duration of time, our impulse could still be okay.
- 10:22Speaker 1: The other way you could do it is shorter window
- 10:25Speaker 1: of that impulse window, but if our peak force is
- 10:28Speaker 1: really high, the impulse could still be a decent number here.
- 10:31Speaker 1: But ideally, we're producing force over a pretty long period
- 10:33Speaker 1: of time while also getting to sharp and high peaks
- 10:37Speaker 1: for this as well. So that's all that shaded area
- 10:40Speaker 1: is showing. The impulse starts right at the peak D
- 10:43Speaker 1: waiting point. So right here, literally where This picture is here.
- 10:46Speaker 1: He has just started to descend from his leg lift
- 10:50Speaker 1: into his stride where he is his lightest. This is
- 10:52Speaker 1: the point where impulse actually starts. Now some systems, and
- 10:56Speaker 1: I think even AxioForce and NewtForce and some of these
- 10:59Speaker 1: other companies, they tend to start the impulse a little
- 11:02Speaker 1: bit further back. Basically, whenever there is an increase in
- 11:05Speaker 1: this Y force, they start to capture impulse. Just from
- 11:10Speaker 1: my learning and understanding from when I was with the
- 11:12Speaker 1: twins and talking to some of the best biomechanists in
- 11:14Speaker 1: the world, One specifically, Martijn, he is absolutely incredible. Worked
- 11:18Speaker 1: with him with the twins. He's now working in basketball
- 11:22Speaker 1: and doing some other various consulting things as well, still
- 11:24Speaker 1: in baseball. And he started or he mentioned starting this
- 11:28Speaker 1: capture right around this point because this is where we're
- 11:30Speaker 1: actually starting to produce force, right? We're not producing force
- 11:34Speaker 1: really at any point before this. As I'm going to
- 11:36Speaker 1: my leg lift, there is going to be a little
- 11:37Speaker 1: bit of that Y force just because I'm getting a
- 11:39Speaker 1: little bit of my center of mass shifted towards home.
- 11:41Speaker 1: But I'm not actually starting to drive. So it could
- 11:44Speaker 1: give a false implication of what that impulse actually is.
- 11:47Speaker 1: So we wanted to make sure that we started this
- 11:49Speaker 1: right when we're actually starting to create that force down
- 11:53Speaker 1: the mound. So for peak Y here, generally speaking, we
- 11:57Speaker 1: want to get to at least 50% of our body weight. Now,
- 12:00Speaker 1: this depends on the velocity bracket that you're in. Like
- 12:02Speaker 1: if you're a high school kid that's throwing 75 miles
- 12:05Speaker 1: an hour, like you getting to 50% of your body
- 12:08Speaker 1: weight for peak Y is probably going to be pretty
- 12:10Speaker 1: big for you. You're probably going to be getting close
- 12:12Speaker 1: to that 80 mile an hour range. Guys that are professionally,
- 12:15Speaker 1: so like this pitcher here that is here, he's throwing
- 12:17Speaker 1: in the low 90s here in this session. His peak
- 12:19Speaker 1: Y force, let's see, I'm going to change that to
- 12:22Speaker 1: body weight because I have it on raw force right now.
- 12:24Speaker 1: So his peak Y was up to 68% of his
- 12:28Speaker 1: body weight. So a pretty big difference from, you know,
- 12:30Speaker 1: say a high school kid, or sorry, 73%. Pretty big
- 12:34Speaker 1: difference from a high school kid trying to get to
- 12:35Speaker 1: 80 miles an hour. Him getting to 50% is pretty important.
- 12:38Speaker 1: For a guy like this that's thrown in the 90s,
- 12:40Speaker 1: we're generally seeing 65% or higher. Now, it isn't necessarily
- 12:45Speaker 1: the more the better. Like if he's at 68 and
- 12:48Speaker 1: we think he should be at 75, it's not just
- 12:50Speaker 1: now all of a sudden we're just going to try
- 12:51Speaker 1: to push as hard as we can off the mat
- 12:52Speaker 1: to create this artificial number to get that. But there
- 12:56Speaker 1: is a combination of all these different metrics that we're
- 12:58Speaker 1: looking at that are going to be indicators of a
- 13:00Speaker 1: hard thrower. So the peak force is one important metric
- 13:04Speaker 1: along with many others that we are starting to dive into.
- 13:07Speaker 1: You know, on this episode, and we can even have
- 13:08Speaker 1: another episode where we go into even deeper layers of
- 13:11Speaker 1: exactly what we're looking for on the curvature of these
- 13:13Speaker 1: lines when the peak force is actually happening. But for
- 13:17Speaker 1: the sake of today's episode, that raw number, we want
- 13:20Speaker 1: to see at least 50%. But once we start to
- 13:22Speaker 1: get into the area of throwing 90 plus miles an hour,
- 13:25Speaker 1: it's going to be closer to that 65 to 70%
- 13:26Speaker 1: as being our benchmark. And remember, so just because this
- 13:33Speaker 1: metric is measuring how much force you are pushing away
- 13:36Speaker 1: from the rubber, this doesn't mean that you wanna try
- 13:38Speaker 1: to all of a sudden jump off of the rubber
- 13:40Speaker 1: or push as hard as you can because that's likely
- 13:43Speaker 1: going to lead to a really pushy lower half. You're
- 13:45Speaker 1: not gonna rotate as well. You're gonna get triple extension
- 13:48Speaker 1: on that back leg way too early and likely you're
- 13:51Speaker 1: gonna be dumping the torso forward a little bit too soon.
- 13:54Speaker 1: So this should be happening with proper sequencing with the
- 13:57Speaker 1: rest of your delivery. It's not just artificially trying to
- 13:59Speaker 1: create a number just for the sake of creating that number.
- 14:03Speaker 1: I always think of when I think of this peak
- 14:04Speaker 1: Y number, I think of a tool. I'm trying to
- 14:06Speaker 1: remember what it was called. I think it was called
- 14:08Speaker 1: King of the Hill that some people still use. It
- 14:11Speaker 1: was this little device where if you pushed up against it,
- 14:13Speaker 1: it made a clicking sound and you could choose how
- 14:16Speaker 1: much tension it required in order to make that sound.
- 14:19Speaker 1: And I remember using this at one point and seeing
- 14:22Speaker 1: other people use it. You literally just start pushing and
- 14:25Speaker 1: jumping as hard as you can to try to make
- 14:26Speaker 1: it click. And, yeah, you're producing the force, so to speak,
- 14:30Speaker 1: in the Y direction, but everything else in your delivery
- 14:32Speaker 1: is going to crap because you're trying just to isolate
- 14:34Speaker 1: this one specific movement of pushing as hard as you
- 14:36Speaker 1: can off the rubber. And that's not what we want
- 14:38Speaker 1: to do. We want to make sure this is properly
- 14:40Speaker 1: sequenced with everything else in the delivery, and it's a
- 14:42Speaker 1: byproduct of moving well down the mound. Our next metric
- 14:48Speaker 1: that we're going to look at is YZ transfer back.
- 14:51Speaker 1: So that is a fancy way of talking about the
- 14:54Speaker 1: back leg specifically. And what is the time difference between
- 14:58Speaker 1: peak Y force and peak Z force? So remember, Z
- 15:02Speaker 1: force is straight down on the ground. Y force is
- 15:04Speaker 1: pushing away from the rubber. Ideally, we want these happening
- 15:08Speaker 1: as close to the same time as possible. So we're
- 15:11Speaker 1: looking at this peak blue line right here. So we
- 15:14Speaker 1: can see where my cursor is. That is peak blue
- 15:16Speaker 1: or peak Z force. And then where this green peak is,
- 15:19Speaker 1: that is peak Y force. Ideally, we want those stacked
- 15:23Speaker 1: as close to possible or as close as they can
- 15:26Speaker 1: as possible. So if we see here for this specific picture,
- 15:30Speaker 1: we can see Z force is happening a little bit
- 15:33Speaker 1: before Y force. And we can see the milliseconds here.
- 15:35Speaker 1: There's a 28 millisecond time difference. Now that might not
- 15:38Speaker 1: seem like a lot, but every millisecond when we're talking
- 15:40Speaker 1: about pitching mechanics, especially force production, is vital. Now I
- 15:45Speaker 1: wouldn't say this is bad necessarily, and we don't even
- 15:47Speaker 1: have necessarily like a specific time range that we're looking
- 15:49Speaker 1: for right now. We're still doing some testing on this
- 15:52Speaker 1: to see what leads to the best results. But generally speaking,
- 15:55Speaker 1: we want them to be overlapped as close as possible.
- 15:58Speaker 1: If you have a guy that is significantly reaching his
- 16:01Speaker 1: peak Z force before Y force, that would be a
- 16:04Speaker 1: sign that he is not gaining any momentum towards home
- 16:06Speaker 1: into leg lift, and he is more of your drop
- 16:08Speaker 1: and drive pitcher. So he is sitting straight down and
- 16:11Speaker 1: then pushing out away from the rubber. Ideally, we're getting
- 16:14Speaker 1: a little bit of that center of mass shift forward,
- 16:16Speaker 1: so the drift in other words. And then as we
- 16:19Speaker 1: go into our sit, because we already have a little
- 16:22Speaker 1: bit of our center of mass going towards home, we're
- 16:24Speaker 1: going to be producing our Y force and our Z
- 16:26Speaker 1: force relatively at the same time. Now, there is such
- 16:30Speaker 1: thing as too much of a drift, as I'm sure
- 16:31Speaker 1: you've heard before. And how this would show up on
- 16:34Speaker 1: a force plate mound would be if I am drifting
- 16:36Speaker 1: too much and I then go into my sit, my
- 16:41Speaker 1: Z force, the blue line, is not going to be
- 16:43Speaker 1: very high, but my Y force still might be okay.
- 16:47Speaker 1: And the reason for that is because I have momentum
- 16:48Speaker 1: going towards home, so I'm going to be able to
- 16:50Speaker 1: push off the rubber decently well But I'm not going
- 16:52Speaker 1: to have enough energy to actually sit down and produce
- 16:55Speaker 1: force straight down into the ground because my momentum has
- 16:57Speaker 1: already shifted way too far down the mound. So there's
- 17:00Speaker 1: a happy medium here that you'll have to play with.
- 17:03Speaker 1: And really, when it comes to the drift, I don't
- 17:06Speaker 1: like guys thinking, hey, let's fall towards home or let's
- 17:08Speaker 1: get our momentum going towards home. I think there's some
- 17:11Speaker 1: subtle things you can do in your delivery to get
- 17:14Speaker 1: that initial move without even thinking about it, whether it's
- 17:17Speaker 1: favoring a little bit more weight on the front leg.
- 17:19Speaker 1: whether it's having your front shoulder slightly lean forward into
- 17:22Speaker 1: leg lift. Whatever it is, there's a few different ways
- 17:24Speaker 1: that we can do this to get our center of
- 17:25Speaker 1: mass moving towards home. And the skill level of the
- 17:28Speaker 1: player is going to matter too. Our younger kids, they
- 17:31Speaker 1: don't have nearly as much body control or awareness as
- 17:34Speaker 1: a college or a professional pitcher. So if I get
- 17:37Speaker 1: their momentum going towards home too soon, they're not going
- 17:40Speaker 1: to be able to capture anything or produce any force
- 17:42Speaker 1: straight into the ground, and they're essentially just going to
- 17:44Speaker 1: fall towards home. Versus our more skilled players and our
- 17:47Speaker 1: stronger players, they're going to be able to get a
- 17:49Speaker 1: little bit of that shift forward while still being able
- 17:51Speaker 1: to stay in the back leg and produce force in
- 17:53Speaker 1: the back leg as well. All right, our next metric
- 17:58Speaker 1: we're going to talk about is peak lead leg Y.
- 18:01Speaker 1: So now we are shifting over to the right side
- 18:03Speaker 1: of the graph here. And Y force, remember, is still
- 18:06Speaker 1: the green line. So now that we're here on the
- 18:08Speaker 1: right side of that middle line, we are talking about
- 18:09Speaker 1: the lead leg. And this is essentially our lead leg block.
- 18:14Speaker 1: This is the metric that you would look at for here.
- 18:17Speaker 1: So first, the raw force number. So how much force
- 18:20Speaker 1: is my lead leg producing in the Y direction? So
- 18:23Speaker 1: essentially pushing back into my body, back towards the rubber,
- 18:26Speaker 1: so I can actually transfer my energy with my upper
- 18:29Speaker 1: body over that front side. Ideally, we want to get
- 18:32Speaker 1: close to 100% of our body weight for that lead leg.
- 18:36Speaker 1: I've seen ranges upwards of 120%. I've also seen as
- 18:38Speaker 1: low as you know, 50, 60% of those are usually
- 18:42Speaker 1: guys that aren't landing very stable on that front leg
- 18:44Speaker 1: and that knee is just collapsing and they are just
- 18:46Speaker 1: continuing to fall towards home. So we want to get
- 18:49Speaker 1: as close to 100% of body weight as possible. And
- 18:51Speaker 1: then that leads into the next metric, which is clawback time.
- 18:55Speaker 1: And then we want to make sure that line is
- 18:57Speaker 1: shooting back up to zero as quickly as possible. So
- 18:59Speaker 1: what that means is we are producing the force, we're
- 19:02Speaker 1: applying the brakes, and now we're transferring the energy back
- 19:05Speaker 1: up the chain. If this line just kind of trickles
- 19:08Speaker 1: and doesn't actually shoot back to zero, that's a sign
- 19:10Speaker 1: that the knee is continuing to collapse and we're essentially
- 19:13Speaker 1: just getting soft into release rather than actually rotating around
- 19:16Speaker 1: a firm front side. Now you don't have to get
- 19:18Speaker 1: completely straight with that lead leg, right? Like lead leg
- 19:22Speaker 1: block has been talked about for many, many years at
- 19:24Speaker 1: this point and everybody has a different opinion on what
- 19:28Speaker 1: a good lead leg looks like. For me, I don't
- 19:31Speaker 1: think the lead leg needs to get completely straight in
- 19:33Speaker 1: a ball release, but it definitely needs to be pulling back.
- 19:36Speaker 1: it's continuing to drift forward that's definitely a no-no like
- 19:39Speaker 1: we're not adequately transferring that energy up the chain and
- 19:42Speaker 1: honestly even if it's just staying in place like yeah
- 19:44Speaker 1: it's not as bad but we're still not transferring as
- 19:46Speaker 1: much force as we could into the lead leg so
- 19:49Speaker 1: ideally I like to see this shoot back up to
- 19:51Speaker 1: zero as quickly as possible. And that's just a sign
- 19:54Speaker 1: that we're quickly transferring energy up the chain into the
- 19:56Speaker 1: upper body. And honestly, I would say that is the
- 19:59Speaker 1: biggest thing that you will see with hard throwers compared
- 20:01Speaker 1: to softer throwers. Yes, the peak forces might be different.
- 20:06Speaker 1: But I've seen a 95-mile-an-hour thrower and an 80-mile-an-hour thrower
- 20:10Speaker 1: honestly have very similar raw force numbers based on their
- 20:14Speaker 1: body weight. Right now, the softer thrower, maybe he weighs
- 20:17Speaker 1: less compared to the harder thrower. But even then, the
- 20:20Speaker 1: force numbers are still pretty similar. What the harder thrower
- 20:23Speaker 1: does differently is he produces that force at a faster rate.
- 20:27Speaker 1: So he's able to transition from one segment to the
- 20:29Speaker 1: next in a much tighter window, which then leads to
- 20:32Speaker 1: higher velocity. So yes, raw force matters. But the timing
- 20:36Speaker 1: in which things are happening and how quickly they're happening
- 20:39Speaker 1: is also super important. And then that leads me into
- 20:43Speaker 1: the next metric, which I think is our last metric
- 20:44Speaker 1: we're going to dive into today. Yep, it is, which
- 20:47Speaker 1: is peak Y transfer. So we're still staying on this
- 20:52Speaker 1: Y category because Y force is honestly, I didn't really
- 20:55Speaker 1: think about it until right now, until after all these
- 20:57Speaker 1: things I've been talking about, about the Y direction. Y force,
- 21:00Speaker 1: in my opinion, is probably the most important metric. with
- 21:04Speaker 1: the back leg and the lead leg because it is
- 21:06Speaker 1: just such a vital engine, so to speak, for our
- 21:10Speaker 1: force for producing on the back leg and then capturing
- 21:13Speaker 1: on the front leg to transfer it up the chain.
- 21:16Speaker 1: So what is peak Y transfer? This is telling us
- 21:20Speaker 1: how long it takes us to go from peak Y
- 21:23Speaker 1: on the back leg to peak Y on the lead leg.
- 21:26Speaker 1: So how quickly am I pushing my hardest off the
- 21:29Speaker 1: back leg And what is the time difference between that
- 21:31Speaker 1: point and when my lead leg lands and produces the
- 21:34Speaker 1: most amount of force in order to transfer energy back
- 21:36Speaker 1: up the chain? The faster that window, the better. And
- 21:40Speaker 1: once again, this is where it comes back to raw force. Yes,
- 21:42Speaker 1: it's important, but the speed in which things are happening
- 21:45Speaker 1: is even more important in my opinion. So this is
- 21:48Speaker 1: one of the more important metrics that we look at
- 21:50Speaker 1: as well. And with a lot of these things, honestly,
- 21:52Speaker 1: like I don't have super hard numbers to this point.
- 21:55Speaker 1: We're still collecting a lot of data and information to
- 21:57Speaker 1: figure out like what is optimal because For every guy
- 21:59Speaker 1: that I see, you know, produces X amount of force
- 22:02Speaker 1: and throws hard, I see the same guy do the
- 22:04Speaker 1: same thing and he's throwing, you know, 10 miles an
- 22:06Speaker 1: hour slower. So we're still diving into these numbers before
- 22:08Speaker 1: we start sharing, you know, hard specifics of what we
- 22:11Speaker 1: want to see, especially with the timing metrics. But just
- 22:15Speaker 1: know that our harder throwers, generally speaking, are producing their
- 22:18Speaker 1: force in tighter windows. Their graphs are smoother with sharper
- 22:22Speaker 1: peaks rather than this bumpy, rigid, rigid hill's that are
- 22:25Speaker 1: showing a lack of rate of force development as well
- 22:28Speaker 1: as just stability throughout their lower half as they are
- 22:31Speaker 1: producing this force. So we covered a lot of ground today.
- 22:36Speaker 1: That was a lot of metrics to go over. And
- 22:38Speaker 1: like I said, there's many more that we could dive
- 22:41Speaker 1: into that are super important. And there might be, as
- 22:44Speaker 1: time goes on, we might learn others that aren't as
- 22:46Speaker 1: important and some that are more important, just like anything.
- 22:49Speaker 1: As we evolve with our teaching and learning and educating ourselves,
- 22:54Speaker 1: hopefully we're positively trending up in order to get better
- 22:58Speaker 1: results for our players. But just to go over those
- 23:02Speaker 1: six one more time. First one we went over was
- 23:03Speaker 1: back leg peak D weighting. So remember, this is the
- 23:07Speaker 1: lightest we are right around peak leg lift. That first
- 23:10Speaker 1: initial move as we go from peak leg lift and
- 23:12Speaker 1: transition to our stride, that is the lightest point we're at.
- 23:15Speaker 1: Generally speaking, we want to be about 50% of our
- 23:17Speaker 1: body weight for that. The next metric we went over
- 23:20Speaker 1: was back leg peak Y. So this is the peak
- 23:23Speaker 1: force we are producing on the back leg pushing away
- 23:26Speaker 1: from the rubber. Number three, we went over was YZ
- 23:30Speaker 1: transfer back. So, so folks on the back leg, this
- 23:32Speaker 1: was telling us what was the time difference between Z force,
- 23:35Speaker 1: which is straight down to the ground and Y force,
- 23:37Speaker 1: which is pushing away from the rubber. Ideally, those are
- 23:40Speaker 1: overlapping as close as possible to each other. Number four
- 23:44Speaker 1: was lead leg peak Y. So this is now shifting
- 23:47Speaker 1: to the front leg. This is the force produced on
- 23:50Speaker 1: that landing leg shooting back towards the rubber. Number five,
- 23:55Speaker 1: lead leg clawback. And then this is just simply telling
- 23:57Speaker 1: us how fast or how long does it take us
- 23:59Speaker 1: to go from that peak force in the lead leg
- 24:01Speaker 1: in the Y direction to transferring that energy up the chain.
- 24:05Speaker 1: And then the last one we went over was peak
- 24:07Speaker 1: Y transfer. So this is talking about the transition from
- 24:11Speaker 1: back leg peak Y to lead leg peak Y. And
- 24:14Speaker 1: ideally that is happening in as small of a window
- 24:17Speaker 1: as possible. So I appreciate you guys listening to today's episode.
- 24:20Speaker 1: Before I let you go, I did want to share
- 24:23Speaker 1: for those of you that are high school players or have,
- 24:26Speaker 1: if you're a coach, if you have players on your
- 24:28Speaker 1: high school team, or if you're a parent listening to
- 24:30Speaker 1: this that has a high school player, we are bringing
- 24:33Speaker 1: back our two day masterclass in Phoenix, Arizona. We've ran
- 24:37Speaker 1: a handful of these over the last couple of years.
- 24:39Speaker 1: We haven't had one for about a year to this point,
- 24:42Speaker 1: but we're bringing it back and super excited for it
- 24:44Speaker 1: because this is really going to be like a two
- 24:46Speaker 1: day intensive where we're going to dive into every aspect
- 24:49Speaker 1: of the pitching delivery, of pitch design, of the mental
- 24:54Speaker 1: side of the game, like literally everything involving pitching and
- 24:58Speaker 1: what it means to be a successful pitcher, we're going
- 25:00Speaker 1: to give you tons of objective information, including this Axial
- 25:02Speaker 1: Force Mound data. So you will be throwing on our
- 25:05Speaker 1: mound where you will be getting all this data. We'll
- 25:07Speaker 1: sit down with you and go over what it means,
- 25:08Speaker 1: what we think the low-hanging fruit is for you, and
- 25:11Speaker 1: give you a plan to actually get better. Because like
- 25:13Speaker 1: I said earlier, information without a plan to get better
- 25:17Speaker 1: and without leading to results is just expensive technology. And
- 25:21Speaker 1: I don't know about you guys, but I don't want
- 25:22Speaker 1: to spend money on things that aren't going to actually
- 25:24Speaker 1: help players get better. So we've invested a lot of
- 25:28Speaker 1: time and money and resources into making these things happen
- 25:31Speaker 1: and with the sole purpose of getting players better. And
- 25:34Speaker 1: we would love to be able to help you if
- 25:36Speaker 1: you're a player or your son or your players here
- 25:39Speaker 1: at our two-day masterclass, which is going to be taking
- 25:41Speaker 1: place on November 7th to 8th. It's a Saturday and Sunday.
- 25:46Speaker 1: It's going to be a full-day Saturday, half-day Sunday. It's
- 25:50Speaker 1: going to be an incredible weekend. We're capping it at
- 25:53Speaker 1: just 10 pitchers. My whole staff is going to be
- 25:55Speaker 1: working with us on this to make sure that we
- 25:58Speaker 1: are giving you incredible information and teaching and letting and
- 26:02Speaker 1: leaving you with a plan when you go back home
- 26:05Speaker 1: wherever you live to be able to get better and
- 26:07Speaker 1: actually take your game to the next level and to
- 26:09Speaker 1: be a resource for you along the way. So if
- 26:11Speaker 1: you're interested in that, you can click the show notes
- 26:13Speaker 1: or if you're watching this on YouTube, just look at
- 26:15Speaker 1: the information below this for a sign up link along
- 26:18Speaker 1: with some more information. to dive into that. So I
- 26:21Speaker 1: appreciate your guys' time. Looking forward to continuing to grow
- 26:24Speaker 1: the podcast. I really enjoyed this. And as time goes on, we'll,
- 26:28Speaker 1: you know, we'll bring on some guests for this and,
- 26:30Speaker 1: you know, maybe my employees will come on as well.
- 26:32Speaker 1: And we'll just kind of talk shop and talk pitching.
- 26:35Speaker 1: So I'll see you guys next time.
